Since the visual appeal of dry cannabis flower plays an important role in the consumer’s purchasing decision, growers can stay competitive by cultivating varieties with a unique visual appearance.
Besides offering consumers well-manicured flowers that are covered in copious amounts of trichomes (the microscopic oil droplets that contain the plant’s active ingredients), growers can stand out by cultivating varieties with red, pink, or purple flowers.
Flavonoids known as anthocyanins are responsible for imparting purple hues to cannabis.
In other plants, such as blueberries and eggplants, anthocyanins impart the red, purple, and blue coloration.
Depending on genetics, pH, and temperature, some cannabis flowers can express a pink, yellow, or even black appearance once they are dried.
Cannabis flowers that are naturally a different color are rare and typically command a higher price at retail.
